The two sides have engaged in skirmishes before but none reached such a level and caused even half
求翻译!
The two sides have engaged in skirmishes before but none reached such a level and caused even half as much worry.So what is different this time?

答案

大致的意思是：
双方之前就有过小冲突,但是从来没有到达这个程度（像这次这么严重过）,也没有令人如此担心过.所以说,这次有什么不同呢
这样的句子,结合现实,应该用在韩朝冲突,或者印巴冲突等等情况下比较多.
